and cristte acusticae of the mouse with results which confirm those of 

 Retzius, that the nerves end free upon the hair-cells without entering 

 their substance. The histogenetic, as well as the trophic centre of the 

 acoustic fibres lies in the auditory ganglion, from whose bipolar 

 nerve-cells one process passes mesally to break. up in a terminal den- 

 drite within the so-called acusticus nidulus, another passes peripherally 

 and ends similarly in intimate contact with the hair-cells.

The discovery of His that in the spinal ganglia the sensory nerves 

 pass both centrally and peripherally from the neave-cell in the gang-" 

 lion and the motor nerves originate within the cord and effect no con- 

 nections in the ganglion accounts for the fact that in the adult ganglia 

 no cells are found with more than two processes. Yet cells of the 

 sympathic ganglia, which originate from the spinal ganglia, possess 

 well-developed dendrites. This fact has led to the study of frog-larvge. 

 In young stages, before the hind legs have appeared, numerous cells 

 are found which possess several proceses, some provided with small 

 but typical terminal dendrites. Further investigations are promised 

 in the near future. 



Notes Upon Hysteria. 



From a series of important articles in the Archives de Neurologie 

 we abstract such portions as may be of service to the theory and prac- 

 ■ tical treatment of these too frequent maladies of an over differentiated 

 society. We owe the greater part of these abstracts to Mr. Charles 

 B. White. First, then, definitions, as supplied by M. Pierre Janet in 

 an article On some Recent Definitions of Hysteria.'-' 



Lasegue says : Under the name of hysteria is designated provi- 

 sionally a uniform number of nervous manifestations preferredly in 

 young women, encountered very rarely in young men, and not de- 

 pendent upon any known lesion of nervous centers. 



M. Babinski shows that it is possible to make this diagnonsis in 

 studying hysteria : 



I. — Symptomatic aspect. 2. — Evolution. 3 — Aetiology. 4. — 

 The influence of various treatments. 5. — The insight furnished by 

 experimentation upon the hypnotics.
